Yes, the rating of a #8 conductor is 40 amps. There might be a problem of getting the wire under the terminal point on the breaker. The only time that this will happen in reality is when the load is at a long distance from the distribution point. The conductor size has to be increased to over come voltage drop on the circuit to the load.

Can you use 10 gauge wire to connect a 2 15 amp outlets to a 30 amp breaker?
no
Can I use 10 gauge wire with a 30 amp dryer?
Typically yes if you use a 30 amp breaker and the dryer uses 230-240 volts.
Is a 12 gauge wire on 20 amp breaker safe for a sub panel?
Yes, if you are running it no farther than 100 feet. If you are going over 100 feet use AWG # 10 wire on the 20 amp breaker.
How big of breaker do you use for 115 volt?
Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
What size amp circuit breaker should be used for a home entertainment system?
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
Is it safe to use 10 gauge wire on a 20 amp breaker for a microwave?
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
Can you use 14-3 wire on a 20amp breaker?
No. A 20 amp breaker needs 12 gauge wire.
What is the wire size required for 1800 watts for lamps?
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
Can you use 10 gauge wire to connect a 2 15 amp outlets to a 30 amp breaker?
no
What size circuit breaker for GFCI circuit in a normal size bath?
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
What gauge wire to run off a 20 amp breaker?
Use AWG 12/2 with ground.
What size wire for 75 feet of wire for a 30 amp 220 volt oven?
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
Can I use 10 gauge wire with a 30 amp dryer?
Typically yes if you use a 30 amp breaker and the dryer uses 230-240 volts.
Is a 12 gauge wire on 20 amp breaker safe for a sub panel?
Yes, if you are running it no farther than 100 feet. If you are going over 100 feet use AWG # 10 wire on the 20 amp breaker.

What breaker do you use for 10 2 wire?
Use a 30 amp breaker.
You bought a rheem heat pump what gauge wire should you use for a 80amp breaker?
My heat pump was professionally wired when built in 2004. Wire is No. 4 AWG with 80 amp breaker
